Why Choose the Mersen 83020119 Surge Protection Device?
The Mersen 83020119 is a high performance Type 2 surge protection device (SPD) designed to protect low voltage electrical installations from transient overvoltages caused by switching operations, grid disturbances and indirect lightning effects. Part of the Mersen Surge-Trap® Pluggable STPT2 Series, it provides dependable protection for commercial, industrial and automation environments.
The STPT2-40K320V-2PGM is designed for 277 V AC 1Ph+N TT systems and delivers a 40 kA maximum discharge current (Imax) together with a 20 kA nominal discharge current (In). Its 1+1 TT configuration protects both line-to-neutral and neutral-to-earth paths, while the integrated remote indication contact enables monitoring of SPD status from a control panel or alarm circuit.
With a 320 V AC maximum continuous operating voltage (Uc), compact 2 pole, 2 module pluggable construction and DIN rail mounting, the Mersen 83020119 is ideal for protecting distribution boards, switchgear, control panels and sensitive electrical equipment in demanding low voltage installations.

Reliable Protection Against Electrical Surges
Type 2 surge protection devices help divert transient overvoltages away from connected electrical equipment, reducing the risk of component damage, nuisance failures and costly downtime. They are commonly installed in distribution boards as part of a coordinated low voltage surge protection strategy.
The Mersen Surge-Trap® STPT2 Series combines high surge current capability with replaceable pluggable cartridges and integrated remote monitoring, making it a practical solution for distribution panels, industrial control systems and commercial installations.
Typical Applications
- Single phase 277 V TT electrical systems.
- Commercial distribution boards.
- Industrial control panels.
- PLC and automation systems.
- Building electrical services.
- Low voltage power distribution equipment.
